Shutdown tasks

[justinmoon]

There doesn't seem to be a way to run scripts on container shutdown. I was running a database that was corrupted between restarts. I assume the process must have been killed before it could properly shutdown, but am not sure.

It would be nice if I could run a little bash script on shutdown that could gracefully stop this service.

I tried adding a script as a CMD in the dockerfile which could trap kill signals (demo

It works locally (to test I change the CMD to run a script that just prints on a loop: while true; do echo "hello"; sleep 1; done)

But when I attempt to build a GitPod workspace I get an error: Error while adding GitPod layer

I mention this because I'm happy to use a hack like this for a while, but I just can't figure out how to get it to work ...

Hi Justin!

Thx for bringing this up. Your demo link, unfortunately, is a 404.

I agree that it makes sense to have shutdown hooks. Using traps seems like a good workaround.

Can you say which database you used and which command the database would have required to run for a clean shutdown?

I too have a case where I'd like to run a command during container stop, so I can close down a database cleanly and avoid recovery steps being triggered on subsequent container start.
